The pain of chronic loneliness can be detrimental to your health
The changes came so gradually that, for a long time, Paula Dutton didn ’t realize she was in trouble. This was just modern life, after all — the cross-country distance from her close-knit family in Philadelphia, the end of a 10-year marriage, the death of one parent and then the other. By the time Dutton retired from her job, she was lonely to a degree that shocked and frightened her.“I just suddenly realized I was all alone and had no one around me and no one I could turn to,” says Dutton, now 71. “I had a lot of pity parties, I can tell you — and with all kinds of anxiety and depression. And I worked myself i...

UCLA study shows how brain begins repairs after ‘silent strokes’
UCLA researchers have shown that the brain can be repaired — and brain function can be recovered — after a stroke in animals. The discovery could have important implications for treating a mind-robbing condition known as a white matter stroke, a major cause of dementia.White matter stroke is a type of ischemic stroke, in which a blood vessel carrying oxygen to the brain is blocked. Unlike large artery blockages or transient ischemic attacks, individual white matter strokes, which occur in tiny blood vessels deep within the brain, typically go unnoticed but accumulate over time. They accelerate Alzheimer ’s disease du...

Analyzing brain patterns may help neuroscientists increase people ’s confidence, reduce fear
A new technique of analyzing brain patterns appears to help people overcome fear and build self-confidence.The approach, developed by a UCLA-led team of neuroscientists, is described in two new papers, published in the journals Nature Communications and Nature Human Behaviour.Their method could have implications for treating people with depression, dementia and anxiety disorders, including post-traumatic stress disorder, said Hakwan Lau, a UCLA associate professor of psychology and the senior author of both studies. It could also play a role in improving leadership training for executives and managers.In theNature Human Be...

Time window to help people who ’ve had a stroke longer than previously shown
Time is of the essence when getting people stricken with acute ischemic strokes to treatment. And the use of stent retrievers — devices that remove the blood clot like pulling a cork out of a wine bottle — has proven to be a breakthrough for removing the life-threatening blockage of blood flow to the brain.Current professional guidelines recommend that the procedure be performed within six hours for people to benefit. But researchers on a UCLA-led study published today in the Journal of the American Medical Association have found that the procedure has benefits for people up to 7.3 hours following the onset of a stroke...

MRI scan may help diagnose chronic traumatic encephalopathy, UCLA researchers report
UCLA doctors have found what may be an earlier and easier way to diagnose chronic traumatic encephalopathy, or CTE, a disorder that is thought to affect some former football players and others with a history of repetitive brain trauma.
Using a new software tool for analyzing MRI scans, the researchers detected the shrinkage of several key brain regions in a former football player with cognitive problems. The same pattern of brain changes is commonly seen in CTE cases that have been confirmed by autopsies after a person’s death.
While the findings from this single case report are preliminary, they raise the possibility th...

Simply moving 30 minutes a day can lower your health risks
If you spend hours commuting to work and sitting at your desk all day, recent studies about the health hazards of too much sitting probably have hit home.
“Humans are not biologically designed to be sedentary,” says Elisa Terry, program director of the UCLA Recreation Fitwell program. “The more you sit, the unhealthier it is for your body.”
Being sedentary increases risks for diabetes, high blood pressure and poor circulation.

To floss or not to floss: That is suddenly the question
For decades, the federal government and dentists have recommended flossing daily to prevent cavities and gum disease.
Now the evidence for flossing appears to be hanging by a string.
The Associated Press announced last week that its investigation of 25 studies on flossing found the data supporting its benefits to be “weak, very unreliable,” while also noting that the federal government’s new dietary guidelines have quietly removed any mention of flossing.
If you’re smiling about the news — a recent study found that nearly one-third of American adults never floss — hold on.
Should you still floss? Yes, say exp...

Latin American, Caribbean health systems need more investment as populations age
The health systems of six Latin American and Caribbean countries have made substantial progress toward universal coverage — providing free or subsidized healthcare to the majority of their populations — but continue to face challenges managing more complex health needs such as those related to cardiovascular disease, cancer, stroke and depression, a new study from the UCLA Fielding School of Public Health and the Inter-American Development Bank finds.
Though the health systems in Brazil, Colombia, El Salvador, Jamaica, Mexico and Panama have considerable strengths, citizens still reported gaps in the way primary care i...

Exercise results in larger brain size and lowered dementia risk
FINDINGS
Using the landmark Framingham Heart Study to assess how physical activity affects the size of the brain and one’s risk for developing dementia, UCLA researchers found an association between low physical activity and a higher risk for dementia in older individuals. This suggests that regular physical activity for older adults could lead to higher brain volumes and a reduced risk for developing dementia.
The researchers found that physical activity particularly affected the size of the hippocampus, which is the part of the brain controlling short-term memory. Also, the protective effect of regular physical activit...

No more sneaking sugar into packaged foods
The iconic black-and-white Nutrition Facts label you find on packaged foods in the United States is getting its first makeover in two decades. The federal government decided last month to update the food label beginning in 2018 by listing how much sugar has been added to a product.
The current label lumps added sugar with naturally occurring sugars in the foods themselves, which is a deceptive practice, said Dr. John Swartzberg, a UC Berkeley clinical professor emeritus and editorial board chair of the UC Berkeley Wellness Letter. So listing added sugar “will hopefully guide people away from consuming products with a ...

UCLA study identifies how brain connects memories across time
Using a miniature microscope that opens a window into the brain, UCLA neuroscientists have identified in mice how the brain links different memories over time. While aging weakens these connections, the team devised a way for the middle-aged brain to reconnect separate memories.
The findings, which were published today in the advance online edition of Nature, suggest a possible intervention for people suffering from age-related memory problems.
“Until now, neuroscientists have focused on how the brain creates and stores single memories,” said principal investigator Alcino Silva, a professor of neurobiology at the Da...

Majority of L.A. tenants favor smoke-free apartments, but 80 percent of units are still not protected
Eight of 10 Los Angeles apartment dwellers are not protected from secondhand smoke, and an even bigger percentage — 82 percent — would support smoke-free policies in their buildings, according to a pair of new studies by the UCLA Center for Health Policy Research.
The research was released today to coincide with the kickoff of a new citywide campaign to reduce secondhand smoke in multi-unit apartment buildings.
The two studies outline findings from nearly 1,000 door-to-door interviews with tenants in some of the most densely populated areas of the city of Los Angeles, as well as reports submitted to UCLA by 93 owner...

Computational tools could change the way sleep apnea is treated
Imagine that before performing surgery, doctors could consult software that would determine the actual effectiveness of the procedure before even lifting a scalpel.
With the use of a computational model of the human airway being developed by Jeff Eldredge, a professor at the Henry Samueli School of Engineering and Applied Sciences at UCLA, people who suffer from sleep apnea may one day benefit from such a scenario.
Previously, Eldredge, a professor of mechanical and aerospace engineering, had been working on creating models that simulated the interactions between blood and vessel walls with Shao-Ching Huang, an expert in h...
